1 Claim.

This invention relates to improvements in receptacles, such as drinking cups, fruit or punch bowls, and the like.

, It is an object of the invention to provide a 5 receptacle having an ice chamber formed in the center of the receptacle whereby the contents of the receptacle may be cooled without the contents coming in direct contact with the ice.

A further object of the invention resides in providing a receptacle of the above-mentioned character which is simple and durable in construction, eiiicient in operation, ornamental in appearance, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals are employed to designate like parts throughout 0 the same:

Figure l is a sectional view of a punch bowl, showing the ice chamber partly in section and partly in side elevation,

Figure 2 'is a top plan view or the punch bowl,

55 showing the ice chamber partly in horizontal section,

Figure 3 is a vertical section oi a drinking cup, taken on the line 3-3 of Figure 4, with the ice chamber embodied in its construction and partly N in longitudinal section, and

Figure 4 is a top plan view of the drinking cup.

In the drawing, wherein for the purpose 01' 11- lustration I have shown a preferred embodiment I of my invention, the numeral I denotes a punch or fruit bowl which may be-constructed 01' glass or other suitable material. The bowl shown is semi-circular shape in vertical cross section and has an inclined flange 6 depending from the bot- 0 tom forming a base for supporting the bowl. A vertical tube 1 is formed integral with the bottom of the bowl and extends upwardly in the center 01' the bowl with its upper end terminating in an enlarged dome-shaped head 8. The lower 5 end of the tube extends through the bottom and is provided with exterior screw threads 9 to' receive the screw cap in which closes the lower end. The outer wall of the tube 1 is polygonal shape, providing a series of spaced vertical ridges 50 ll and the outer surface of the dome-shaped head I is provided with a series of spaced spiral ridges I2. The ridges II and I! serve to agitate the liquid in the bowl, when stirred.

InPigures3and4,aglassdrinkingcup llis shown, having a central vertical tube l4 forming an ice chamber. The tube I4 is tapered towards its upper end, which is rounded, as at l5, and the outer side wall of the tube is provided with spaced spiral ridges l6 which serve to agitate 5 the liquid in the cup, when stirred. The bottom I! of the cup is spaced upwardly from the lower end of the cup and the lower end of the tube H extends through the bottom and has exterior screw threads I8 to receive a screw cap 10 i9 closing the lower end of the tube.

In operation, the ice chamber of the bowl shown in Figure 1, or the drinking cup shown in Figure 3, is filled with ice which is placed in the chamber by removing the screw caps closing 5 the lower end of the tubes forming the ice chambers. With the ice chambers filled with ice, the liquid contained within the bowl or drinking cup will be cooled by contact with the ice chamber without the liquids coming into direct contact with the ice. This prevents diluting oi the liquid. The ridges provided on the outer wall of the ice chamber facilitate cooling of the liquid by increasing the agitation of the liquid when stirred. While the receptacles are primarily intended for cooling liquids to be consumed, the bowl may also be employed to hold fruit, the ice chamber serving to keep the fruit in a refrigerated condition to prevent spoilage. In practice, it has been found that the best results are obtained if the capacity of the ice chamber is equal to one-third the capacity of the bowl.

It is to be understood that the forms of my invention herein shown and described are to be 85 taken as preferred examples of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

A cooling device comprising a receptacle, a central refrigerant chamber extending upwardly from the bottom of the receptacle and formed integral therewith, the bottom of said chamber being open and surrounded by a screw-threaded collar beneath the bottom of said receptacle, a series of spaced raised longitudinal ridges formed on the outer wall of said chamber, said ridges being tapered to a sharp edge, and a screw cap for engagement wtih the screw-threaded collar to close the open end of said chamber.
